Complaint of dial clunking round – does the usual preselector thing, clunks forward to fill, then again to heat – but – no heat. I assume it’s timing out and aborting to the end.
Heater and NTC are functional, so the question is board or timer? Heater feed is off the p/sw and front row of the timer unit, but I assume that it’s controlled by the board. Unless it stops heating by advancing the timer?
I had a very similar problem to this – the timer kept aborting when washing. It ended up being the PCB causing the fault. Took a while to sus it out though…..
